Add dt-bindings for Imagination E5010 JPEG Encoder [1] which is implemented as stateful V4L2 M2M driver. The device supports baseline encoding with two different quantization tables and compression ratio as demanded. Minimum resolution supported is 64x64 and Maximum resolution supported is 8192x8192.
